This invention relates in general to supporting members for springs of spring constructions, and, more particularly to supporting rails for sinuously corrugated wire springs assembled to wire constructions.

The primary object of this invention is the provision of a rail memberadapted to readily removably and. non-shiftably support corrugated wire springs of the type embodying left and righthanded loops connected with each other by cross wires, the rail member including for each spring two aligned, hook-shaped elements positioned in laterally-spaced, reversed relation with respect to each other for seating and gripping opposite sides of a cross wire of a corrugated wire spring when such cross wire is shifted into engagement with said elements, another hook-shaped element symmetrically spaced from said two elements and constructed to grip the cross wire adjacent to said first cross wire, and struck-up means positioned in offset relation with respect to all said elements and adapted to engage the loop. connecting the said two cross wires to releasably lock the corrugated wire spring in proper position without deforming the rail member and the hook-shaped elements thereof.

Another object of the invention is the provision of a rail member adapted to readily removably zindnon-shiftably support sinuously corrugated wire springs embodying left and righthanded lOOps connected with each other by cross wires, the rail member including for each spring two, aligned, struck-up portionsof hook-shaped form arranged in laterally-spaced, reversed relation with respect to each other, adapted to seat and grip opposite sides of a cross wire of a corrugated wire spring when such cross wire is shifted into engagement with said struck-up portions, a third struck-up portion of hock-shaped form positionedin symmetrical spaced relation with respect to said first two struck-up portions and'adapted to grip across wire adjacent to the said first cross wire of the corrugated. wire spring, and a struck-up stop member positioned in offset relation with respect to said first struckup portions adapted to engage the loop connecting said cross wires of the corrugated wire when said cross wires thereof are shifted into engagementwith the hook-shaped, struck-up portions of they rail member.

A further object of the invention is the provision of a rail member of the type described above in which the struck-up stop member includes a stop shoulder arranged at a right angle to the rail-member and adapted to contact the said loop.

7 Claims. (01. 155-179) of the corrugated wire spring when seated on the rail member and engaged with the struck-up, hook-shaped portions thereof.

Still another object of the invention is the provision of a rail member of the type described above in which the portion of the rail member having the aligned hook-shaped portions struck up therefrom is insulated by a strip of fibrous material formed with struck-up portions for cooperation withthe hook-shaped portions in insulating the cross wires held thereby and avoiding direct. contact of. such cross wires with the rail member and the. hook-shaped portions there- With the above and other incidental objects in view, theinvention has other marked improvements and superiorities which radically distinguish same from presently known structures. These improvements andsuperior characteristics, embodying certain novelfeatures of construction and relation of partsare clearly set forth in the. appended claims and the preferred embodiment of the invention hereinafter shown with reference to the accompanyingdrawing forming part of the specification.

. In the drawing: Fig. 1 is a fragmentary plan view of a rail member. constructed in accordance with the invention, the rail member having removably secured thereto a convolution of a sinuously corrugated wire spring;

Fig. 4 is a view similar to Fig. 1 showing in dash-dotted lines, resting on the rail member, a corrugated wire spring positioned to be shifted so that two adjacent "cross wires of the spring engage withthe hook-shaped, struck-up portions of the rail member; 7

Fig. 5 is'a plan view similar to Fig. 4 showing in dash-dotted lines a position of the wire spring while the two adjacent cross-wires of the wire spring are being shifted into engagement with the struck-up portion of the rail member, and in full linessaid cross wires fully engaged with the struck-up portions and the loop connecting the cross wires contactedby the upwardly bent stop member.

Fig. 6 is a sectional view taken on line 6-6 of Fig. 5.

I Referring now in detail to the exemplified form of the invention shown in the drawing, reference numeral 2 denotes a flanged, U-shaped rail memshaped portion In positioned in spaced, symmet rical relation with respect to. a struck up:hookshaped portions 8 and 9. 'Ifhee'lattemportionsaare:

struck up from seating portion 3 by shifting said seating portion so as to form oppositely extending tongue members II and I2; tongue member" H being bent upwardly and inwardly and tongue member l2 being bent upwardly and outwardly. The thus formed, hook-shaped portions 8 and 9 include upper wall portionsspaced fromseating portion a distance approximately equal to the gage of the wire of: the sinuously corrugated wire spring It, the cross wire: [1- of. which isjengaged and held by portions 8" and 9; Hook-shaped portion ID,w which is positioned in spaced, symmetrical relation with respect to hook-shaped portions-band. 9-, is also struck up from seating portion 3 slit for. this purpose; to form a tonguemember |8=bent upwardly and outwardly to provide a. seat IQ for' cross wire.2B adjacent and parallel: to-cross wire ll of. con- Volution 2| of the sinuously corrugated wire spring is.

' The described. three hook-shaped portions 8, 9 and I which forma group removably seating, holding and gripping sinuously corrugated w-ire spring l6, cooperate witha stop member 22"st'ruck up from resting portion'3 ofrailm'ember 2; This stop member is positioned'in laterally andangularly offset relation with respect to the two liook-' shaped portions 8; San'd hook -shaped portion It! to contact loop 24'forming part of convolution 2|; Stop member 22 is formed by'a Ushaped slit I 4 in resting portion 3 and forcing the'slitted area upwardly when the convolution 2'1 of wire spring I6 is properly seated inhook-shapedportions 8; 9 and It to lock such convolution against accidental displacement.

Mounting of a corrugated wire spring It) on rail member 2 is eifectedby placing'the spring, as shown in dotted lines in Figs. 4 and 5, onthe seating surface of seating portion 3 sothat'cross wire ll extends between the hook-shaped portions 8 and s and has the cross wire ZO'positioned to be shifted into seat-i4 of hook sliaped' portion it from one side thereof; In this position spring i8 is rotated ina direction indicated by arrow 25 to extend cross wire l7. under wall portions i4 and H: of hook-shapedportionsB and 9 and slide into hook shape'd portion l0" ('s'ee'Figs. 4, and untilconvolution 2i properly rests in hook-shaped portions 8, Sand I0. When thus seated the slitted portion in resting portion 3 is forced. upwardly to engage loop H and prevent as stop member 22 rotation ofconvolution-2i in a direction indicated: by: arrow- 26;. A rotation o'fconvolution 21 in the direction indicated by" arrow 25 is prevented by hook-shaped portions 8 and Baas will readilybe seen from the full" line position of spring 16 (see Fig. 5).

Demounting ofcorrugatedfwirespring 16" from rail member 2' can.- be efiecte'd only after stop member 22 has been forced. downwardly into-the resting surface to permit rotation of convolution 2| in the direction of arrow 26.

A direct contact of convolution 2| with seating portion 3 adjacent to hook-shaped portion 8 and 9 and such hook-shaped portions is prevented by a strip 21 of insulating material such as fiber placed on seating portion 3.. This strip includes struck-up tongue members 28 which are arranged to align with the edges of the upper wall portions of hook-shaped portions 8 and 9. Ifhese tongue members which are pliable to permit" th'eirwrapping around cross wire I! when spring, l6 is-being rotated into engagement with hook-shaped portions 8, 9 and In in the manner 2 described: above, insulate the cross wire H from direct contact with seating portion 3 and hookshaped. portions 8 and 9.

To facilitate assembly and disassembly of springs. l6: from rail member 2, hook-shaped portions 8 and 9 have their opposing corner edges at their upper wall portions cut on slanting; parallel lines'2'9 and 30;
